PMCS PROCEDURES - Continued
NOTE
An inactive weapon is a weapon which has been stored in an arms room for a period
of 90 days without use. The weapon may or may not have been assigned to an
individual. Inactive weapons shall receive quarterly PMCS unless inspection reveals
more frequent servicing is necessary. Normal cleaning (PMCS) of an inactive weapon
will be performed every 90 days. If corrosion is detected on a weapon prior to the end
of the 90-day period, the PMCS should be performed immediately.
Solid film lubricant (SFL) is the authorized touch up for the M16A2, M16A3, and
M16A4 Rifle and M4/M4A1 Carbine and may be used on up to one third of the
exterior finish of the weapon.
FOR ARMY CONUS USE ONLY AND AIR FORCE TRAINING WEAPONS ONLY:
Solid film lubricant may be used as a touch up without limitation on the upper
receiver and barrel assembly. Units which DO NOT fall under the category of
Divisional Combat Units or rapid deployment type units may have up to 100 percent
of the exterior surface of the upper receiver and barrel assembly protected with SFL.
Prior to application of SFL, the surface must be thoroughly cleaned and inspected for
corrosion and/or damage. If corroded or damaged, the part must be repaired or
replaced prior to application of SFL. Continued use under combat conditions would
result in an unprotected surface when the SFL wears off. This would result in a
large light reflecting surface and accelerated deterioration of the unprotected surface.
Therefore, Divisional Combat Units and units which fall under the definition of
Rapid Deployment type must adhere to the limitation of NOT over one third of their
exterior surface covered by SFL.
When determining mission capability, deadline if it is a deficiency.
